The official guide to Australia's iconic national parks

When temperatures soar there is a risk of serious heat-related incidents. These tips should help you get the most out of your holiday even if the mercury is rising. When it’s very hot it’s important to walk only in the cooler parts of the day – in summer we strongly recommend you walk only in the early morning, before 11.00 am.

Before you head off to the beach, or set out to walk, familiarise yourself with the symptoms of dehydration and heat stress. In an emergency call 000 or or use an emergency alarm.
